And we should make the penalties heavier for those who commit homicide with angry premeditation, and lighter for those who do not premeditate, but smite upon the instant; for that which is like a greater evil should be punished more severely, and that which is like a less evil should be punished less severely: this shall be the rule of our laws.
CLEINIAS: Certainly.
ATHENIAN: Let us proceed: If any one slays a freeman with his own hand, and the deed be done in a moment of anger, and without premeditation, let the offender suffer in other respects as the involuntary homicide would have suffered, and also undergo an exile of two years, that he may learn to school his passions.

But he who slays another from passion, yet with premeditation, shall in other respects suffer as the former; and to this shall be added an exile of three instead of two years--his punishment is to be longer because his passion is greater.

The manner of their return shall be on this wise: (and here the law has difficulty in determining exactly; for in some cases the murderer who is judged by the law to be the worse may really be the less cruel, and he who is judged the less cruel may be really the worse, and may have executed the murder in a more savage manner, whereas the other may have been gentler.

But in general the degrees of guilt will be such as we have described them.

Of all these things the guardians of the law must take cognizance): When a homicide of either kind has completed his term of exile, the guardians shall send twelve judges to the borders of the land; these during the interval shall have informed themselves of the actions of the criminals, and they shall judge respecting their pardon and reception; and the homicides shall abide by their judgment.
